What are the key points of the correct method for injecting poultry
In poultry farming, injecting poultry is routine, but many farmers do not understand the properties of the drugs, choose the wrong injection site, and use the wrong method, so that after the liquid medicine is injected into the body it flows back out, the injection site becomes inflamed and swollen, and sometimes the poultry die or become paralyzed, bringing unnecessary economic losses to the farm. Therefore, the author suggests that injecting poultry must be done with attention to method.
Do not inject into the inner side of the leg. This is because the main blood vessels and nerves in poultry legs are on the inner side, and injecting here easily causes damage to blood vessels and nerves, leading to bleeding at the needle hole, lameness, paralysis and similar problems.
Do not use a thick needle for subcutaneous injection. A thick needle makes a small depth and a large needle hole, so the liquid medicine easily flows out after injection, and it easily causes inflammation and bleeding. Therefore, subcutaneous injection, especially for injecting chicks, should use a fine needle (a human-use needle), and oil-based vaccines may use a slightly thicker needle.
Do not insert the needle vertically when injecting the chest. When injecting young poultry and chicks, because their muscles are thin, vertical insertion easily penetrates the chest cavity and injects the liquid medicine into the thoracic cavity, causing death. Therefore, follow the direction of the breastbone, insert beside the breastbone, then pull back the plunger and take it as correct if it does not draw back (indicating the needle is in the muscle); at this point push the syringe forcefully to inject the liquid medicine.
Do not inject at a single point when there is a large amount of liquid medicine. Because poultry muscles are thinner than those of pigs, cattle and others, injecting a large amount of liquid medicine at one point easily causes local muscle damage and is also not conducive to rapid drug absorption; the liquid medicine should be injected into the muscle in several divided doses at multiple points.
Do not inject highly irritant liquid medicines into the leg. The leg is the main organ of activity for poultry, and some drugs are highly irritant and slowly absorbed, such as penicillin, oil-based vaccines and others; injecting these drugs into the leg muscles causes long-term leg pain and difficulty walking, affecting feeding and growth and development. Therefore, choose the wing or a part of the chest with more muscle for injection.
Control the force when catching poultry. When injecting, catching poultry should be firm but not injure the poultry. If the force is too great, at best it easily causes enlargement of the needle hole, tearing, bleeding or outflow of the liquid medicine, affecting drug efficacy, and at worst it causes insertion into important parts such as the heart and lungs, leading to internal bleeding and death.
